Heating of a Molecular Cloud by a Primordial Black Hole
A. N. Melikhov, E. V. Mikheeva
The heating of a molecular cloud by photons emitted by a primary black hole (PBH) located inside the cloud is considered. For graphite and silicate dust particles, the dependence o…

Constraints on primordial black holes from interstellar dust temperature in the Galaxy
A. N. Melikhov, E. V. Mikheeva
The photons emitted by primordial black holes (PBHs) can be a heating factor for interstellar dust. Assuming that dust in the Galaxy has a homogeneous distribution and that PBHs ha…

Constraints on the Number of Primordial Black Holes Due to Interaction with Dust
A. N. Melikhov, E. V. Mikheeva
Photons emitted by primordial black holes (PBHs) due to the Hawking effect are among the factors of interstellar dust heating. Based on the data on the temperature of dust, constra…
